The airport has frequent close calls with storms. Gilbert Neil, the airport’s director of public safety, said officials they try to put people in shelters which consist of restroom areas. He said people in those areas are away from glass and debris.

Shuttle service driver Mark Land said everyone is instructed to go to the restrooms during tornado warnings.

“They’re in the center of the building and the most secure place in the building,” Land said.

Airport officials said they are ready and well-practiced for whatever may develop Wednesday and Thursday.

Officials with the Transportation Security Administration, ticketing agents and law enforcement also help direct people to the shelters once a tornado warning is issued for the area.
